Music students download the technique of their favorite pianist or singer directly into their brains. Medical students download the skills of a seasoned surgeon or diagnostician. And each one of us routinely uploads our thoughts and memories to the digital cloud. While these scenarios still lie in the future, rudimentary versions of the necessary brain-to-brain technology exist today. But the ability to directly influence another person’s brain raises serious questions about human rights and individual freedoms. This program will present the latest technology and explore how the ethical implications of enhanced thinking go to the heart of consciousness itself.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Our media partner for this program is Popular Science.

Professor Eric Laithwaite (1921-1997) of Imperial College London demonstrates the difference between magnetic and electro-magnetic motors. Examples futuristic - include minute pump that can fit inside human tissue and a huge test rig to help develop high speed vehicles driven by a linear motor.

This is one of a series of 16mm colour films made for schools. They were all made in Eric Laithwaite's "Heavy Electrical Laboratory" in the Electrical Engineering Department at Imperial College London.

Please turn on subtitles with the CC (Closed Captions) button to see the explanatory annotations designed for educators.

Transcript of closed captions:

0:05: We are approaching a redwood tree. To animate a scientifically accurate leaf, artists studied the texture of a redwood leaf specimen on a glass slide at high resolution. They even counted the stomata, and used that exact count for this film!

0:25: These leaves would be measured on a centimeter scale. Throughout the animation, we will gradually zoom in to smaller scales.

0:40: As we approach a single stoma, we are now on a millimeter scale.

0:48: As we enter the interior of the leaf, we see many individual palisade cells. These cells are where photosynthesis takes place; they are translucent to allow sunlight to enter.

1:00: As we approach a single palisade cell, we’ll zoom down to the micrometer scale. The shapes inside the cell are organelles: the bright globules at the bottom are the Golgi apparatus; the yellow spotted tubes are endoplasmic reticulum studded with ribosomes.

1:09: That large, blue membrane surrounds the nucleus; the purple blobs are mitochondria.

1:18: The faint, yellow, spider-web structure of the cytoskeleton provides structure and support to the cell.

1:24: You are about to enter a chloroplast; inside you see flat, pancake-like membranous structures called thylakoids. This is where the light-dependent reactions of photosynthesis take place to produce ATP, the cell’s energy carrier molecule. way


1:38: The time scale has changed: the molecules are shown moving 1 million times slower than in real life!

1:42: As we near an individual thylakoid, the animation scale continues to shrink down to the molecular level, where things are measured in nanometers.


1:52: The green and blue bush-like structures are photosystems: clusters of proteins that absorb light energy from the sun and help convert it into the chemical energy that’s stored in the bonds of the energy carrier molecule called ATP.

2:03: The yellow-green, rotating structure is an enzyme called ATP synthase. This molecular machine facilitates the flow of protons down their concentration gradient from one side of the thylakoid membrane to the other, using the energy released in the process to assemble ATP.

2:16: The pulses of light in the thylakoid membrane in which the photosystems are embedded represent energized electrons being passed from one photosystem to another, passing along the energy which will be stored in the bonds of ATP (the classic “bucket brigade”).

2:26: The small “wigglies” are ATP molecules. Living things store energy in the bonds of the ATP molecules and then use that energy to conduct all the processes of life.

This animation is a model, and has its strengths and limitations. In order to model something well, visual artists have to make decisions about what to represent and how best to do so.
